A STUDY OF FRACTURE PHENOMENA.
Abstract
Uniformly moving dislocations in anisotropic media is analyzed. The analysis has been developed not only for diad axes (for which the edge and sdrew components of a dislocation can be treated separately) but also for the case of arbitrary orientation (for which both a pure screw and a pure edge involve three components of displacement). Utilization is made of the analysis to study the dynamic behavior of dislocation in the primary slip systems of both fcc and bcc crystals. Edge dislocations lying along various diad axes in a number of cubic and hexagonal materials are also considered. Of primary interest are he calculation of the force between two like parallel dislocations and the determination of whether or not there exists a velocity range in which this force (usually repulsive) is an attractive one. In those cases for which the force can be attractive, the width of the velocity range of anomalous dynamical behavior is computed for various materials. (Author)
